Barataria Pass at Grand Isle, LA

Water temperature for trout, salmon and steelhead

Federal guidance. We found no Louisiana agency water-temperature line for trout anglers. The lines below are the National Park Service's, federal guidance, not a Louisiana rule:

• Stressful for trout. Water 78.4°F now; the highest in the last 24 hours was 80.1°F. At 68°F the U.S. Fish and Wildlife Service says rainbow trout “start stressing”, and the National Park Service at Grand Teton recommends that anglers “cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F.” Its advice: “Fish early in the morning while the water temperature is cooler”, “Play and land fish quickly to reduce exhaustion stress” and “Keep the fish in the water as much as possible.”
